IM movement IN SASH FASTENE RS.

Specification forming part of Letters Patent No. 205,403, dated June 25,1878; application filed April 4, 1878.

To all whom it may concern:

Be it known that I, FREDERICK MARTEN, of the town of Sodus, in thecounty of Wayne and State of New York, have invented a new and usefulImprovement in a Combined Sash Holder and Look, of which the followingis a specification The invention relates to a combined sash holder andlock.

The invention consists in a spring bolt which passes through aface-plate, having a pin controlling its projection and a shoulder,

in forming whichlthe back part of the bolt is diminished to a stem, thesame passing through a washer to the inner edge of the stile, where ithas a thumb-nut, and in a coil spring which is held between saidshoulder and washer; also, a curved lug on thebaok of the face-plate,having an offset and anotch combined with the face and back plates,between which is a roller; also, studs With washers and coil-springsheld between said washers and the back-plate.

In the accompanying drawings, Figure 1 shows the invention applied, Fig.2 being the face-plate; Fig. 3, the back-plate and Fig. 4 is the notchedlug.

F is the face-plate, having a slot, 1, for the roller, the plate beingsunk flush with the stile, to which it is attached by screws 0.

D D are studs solid with and projecting from the back of the face-plate,about onefourth of an inch in diameter, and extending about an inch intothe stile.

B is a perforated loose back-plate, lying fiat to the face-plate, havinga slot, Z, opposite to the slot in the face-plate, with a hole, 0, ateach end for working onstuds D D. The plate is re-enforced by the ears Pfor forming bearings forthe roller.

R is the roller, operating in slots l 1, its journals a rotating onbearings t, which are formed in cars P, a part of its peripheryprotruding infront of the face-plate.

G G are coil-springs on the studs, having one end bearing against theback-plate and the other against the washers W W, which are riveted tothe back ends of these studs.

T is the springbolt. Its locking end 0 protrudes through an orifice, k,in the faceplate, and the diminished end 70 passes through an orifice,1", in the elongated washer w, thence extends through to the inside edgeof the stile, and has a thumb-nut, t, screwed on its end for operatingthe bolt. The coil-sprin g n is on the stem of the bolt, one endpressing against the washer and the other end against the shoulder d ofthe bolt.

j is a cross-pin through the bolt, which, by resting against the back ofthe face-plate, prevents the bolt from protruding too far in front ofthe same.

The lug u is curved around the orifice k, and solid with the back of theface-plate. On the top of this ing is an ofi'set or notch, h, and at itsbase on the opposite edge there is another notch, h. Thebolt is heldback in the stile by resting the pin on this offset h, and it is lockedin the frame by turning the pin into the notch h.

The operation of the invention is as follows: Thedevice being appliedtothe sash, and the stem of the bolt coming through to the inner edge ofthe stile, the thumb-nut t is turned on the stem. By this nut the boltis drawn from the frame into the stile, and by restingthe pin j on theoffset h it is retained therein.

The springs G" press the back-plate to the face-plate, which protrudes aportion of the roller in front; but in applying the sash to the frameboth the roller and back -plate are forced in on the springs, therebyincreasing their power to press out the roller to the jamb. In makingthe springs this power is regulated to hold sashes of different weightsin the frame; but if the jambs are sprung or spread apart the springsmay not be strong enough to hold the raised sash, in which case, byturning the pin j from the ofiset h, the bolt is released and enters anypreviouslymadeholes in the jamb, thereby aiding or of itself holding upthe sash. V

By making holes at suitable points in the jamb the bolt will lock thesash either to the top or bottom of the frame, and by turning said pininto the notch h the bolt islocked to the window-jamb; then, whileinthis condition, by taking off the nut t, both the sash is locked to theframe and the bolt locked in the stile. A cavity (not shown) in the jambrelieves the pressure of the springs by the In testimony whereof, I havehereunto, in presence of these two witnesses, subscribed my name atRochester, Monroe county, New York, on this 27th day of March, 1878.
